[Failure store] Support failure store for system data streams (#126585)
In this PR we add support for the failure store for system data streams. Specifically: - We pass the system descriptor so the failure index can be created based on that. - We extend the tests to ensure it works - We remove a guard we had but I wasn't able to test it because it only gets triggered if the data stream gets created right after a failure in the ingest pipeline, and I didn't see how to add one (yet). - We extend the system data stream migration to ensure this is also working.
